WEIGHING 'SCALE.

Application fil'edfApril 6,'

relates to weighing scales.

The presentinvention isan improvement upoii, or a developinent fortli inLetters 20, 1923.

Patent grantedto of, theV invention set me March ln the above-mentionedpatent, the fundamental idea is ordinary inetliods of to weigh in:reverse of 'f the cweighing. That is to sav, the material is placed oiithe scales in bulk, the indicating hand is placed'at zero and as thematerial is removed, the^hand indicates the amount removed;

inyrpresent invention is to The object of provide a means to cause thepinion: of lthe scales to be'so engaged'with the rack that it willrotate either i clockwise direction acc by a simple that ithe rack adjustmen can be Vdisen in other words,

in neutral position..

egoing' obiect in view, this p VVith the for invention consists o n aclockwise or counter ordiiigly: as. desired t of the rack, or so gagedaltogether placed f a double vrack arranged astride the pinion andadapted to be moved so that the desire mesh with the-pi the scales areto i'eversed weighing, tion with neither rack inv e the teeth of thepinion.

nected., to the lower end of the frame 5 is a similar beam 8, which islikewise pivoted at its opposite end, as at 9, to the casing 1.

A' vertically-arranged spring 10 is adjustably secured at its upper end,as at 12, toy the casing 1, and the lower end thereof is' secured .as at13 to the frame 5.

Av double rack 14 is inovably mounted astride` a pinion 15 and, wliileit inay be mounted in various ways, as a convenient means it is heldpivotally attached to'some pai-t of the .frame 5 by a screw or pin 16. Ahandle or equivalent means 17 projects through on opening inthe 'topofthe casing 1 as a ineans for shifting the rack. In the particular formshown, the entire device presents the general appearancey of an invertedletter Y, the two divergingffrom the center in order to .bring one setoftteethf'oi' the other into the proper vertical position with relationto :the *teethv of the piiiion it; asthe 'receiver ofthe scales iii theweighingoperation, orto a neutral7 position with neither rackinVengagement' with the pinion when desired,

The doublerack lt are so arranged asto effect either a clockwise or acounter-cloclnvise movement to astubshaft'21, to which the pinionil' iskeyed, according'to the` set or adjustment of the rack.

VVh'ile any means' of 'fasteniiig theV double rack in position mightbe'` employed, the meanssh'own is a siinple method and includes a ridge18y on the projecting handle 17 v and a spring keeper part of the frame,so as to embrace the handle, and this spring keeper is provided withthree notclies 20 as shown in Figs. li and 5 into which the ridge 18fits to locl: the double rack in adjustedposition.

An indicating hand 22 Vis removabiy and resettably secured to the stubshaft 21 and is provided with a knob 23 for convenience in setting andresetting the hand.

Aj dial 24 is arranged upon the face of the casing 1, and at the zeropoint of the dial, afpinf26 may be placediasameans for settingforresetting of the hand although it.

is obvious that this pin may be dispensed with altogether, it beingusedas a matter of convenience.

If desired to weigh in the manner of ordinary scales, the operatorreverses the handle 17, that is to say, pushes it to the vsets fof rackteeth and the pinion 15v 19 secured. to some right throwing the righthand side of the rack into mesh With the teeth of the pinion, andproceeds as he Would with anjv ordinai-j7 scales. Bv moving the hand 17to the central notch 20. the double rack assumes a "tneutral position.

.in the use of these scales, for instance, in the feeding of live-stock,the handle 17 could be set at neutralii, i. e. with neither set of rackteeth in eng gement With the pinion and a quantity7 of material could beplaced on the receiver of the scales, as the amount is WholljYimmaterial. Or, if desired, by pusl'iing the hand lever l? to the rightto bring` the right hand set of teeth into mesh vith the teeth, thematerial can be weighed as it is put on the receiver of the scales todetermine the gross Weight, and thereafter changed to weigh off byreversing the hand lever l?, or pushing it to the left, then as a rationis removed from the receiver, say tWo pounds, the indicating hand 22ivill move in a clock-Wise direction until the desired amount isremoved. The hand is then resefi to Zero and the operator repeats theoperation as often as desired.

A further illustration of the convenience and simplicity of theinvention is shown in adapting it to the handling of baggage. In thiscase Where a truck is used, the truck, togethcr with its load, is rolledupon the scales, the Weight of the truck or the men on the truck beingin material. Then as each rticle is removed from the truck, the Weightof that particular article is indicated b v the indicating hand andlikewise the Weight of each and every article removed therefrom may bereadilj.v determined by re-setting the indie-ating` hand for the removalof each article.

It is apparent that inore or less slight changes might be made in theconstruction sho'ivn Without departing from the spirit of the invention,the construction illustrated being onlj7 ono of many that my inventioncon'prehends and is intended to cover.
